debuginfo: add compiler option to allow compressed debuginfo sections

LLVM already supports emitting compressed debuginfo. In debuginfo=full builds, the debug section is often a large amount of data, and it typically compresses very well (3x is not unreasonable.) We add a new knob to allow debuginfo to be compressed when the matching LLVM functionality is present. Like clang, if a known-but-disabled compression mechanism is requested, we disable compression and emit uncompressed debuginfo sections.

The API is different enough on older LLVMs we just pretend the support
is missing on LLVM older than 16.

This directory currently contains some LLVM support code. This will generally
be sent upstream to LLVM in time; for now it lives here.

NOTE: the LLVM C++ ABI is subject to between-version breakage and must *never*
be exposed to Rust. To allow for easy auditing of that, all Rust-exposed types
must be typedef-ed as "LLVMXyz", or "LLVMRustXyz" if they were defined here.

Functions that return a failure status and leave the error in
the LLVM last error should return an LLVMRustResult rather than an
int or anything to avoid confusion.

When translating enums, add a single `Other` variant as the first
one to allow for new variants to be added. It should abort when used
as an input.

All other types must not be typedef-ed as such.
